- 在瘤学瘤学.
- 免疫治疗是一种免疫疗法.
- 生物标志物发现发现
背景情况:
- 与免疫相关的不良事件 (irAEs) 在免疫检查点抑制剂 (ICI) 治疗癌症时很常见.
- 严重的irrAEs可能会导致治疗中止,并影响患者的生活质量.
- 识别irAEs和预后的生物标志物对于优化ICI治疗至关重要.
研究的目的:
- 研究离子度作为irAEs的潜在生物标志物.
- 探索ICI治疗的肺癌患者的离子水平和预后之间的关联.
- 为了确定irAEs和无进展生存率 (PFS) 的预测因素.
主要方法:
- 对459名用ICI治疗的肺癌患者进行了回顾性分析.
- 系统地收集患者特征,离子度 (K +,Na +,Cl-,Ca2+,PO43-,Mg2+),irAEs和预后.
- 应用单变量和多变量回归分析 (逻辑学和考克斯模型).
主要成果:
- 82.4%的患者经历了irrAEs,心脏毒性,甲状腺功能低下和皮肤毒性是最常见的.
- PD-L1表达,ICI周期,客观反应率 (ORR) 和疾病控制率 (DCR) 与irAE发生有关.

Treatment Resistant Cancers
Cancer is the second leading cause of death in the United States. A cancer cell is genetically unstable and hence can mutate faster. They can also modify their microenvironment and escape immune surveillance. The difficulties in treating cancer are further compounded by the emergence of rapid resistance to anticancer drugs. The most common ways to attain resistance in cancer cells include alteration in drug transport and metabolism, modification of drug target, elevated DNA damage response, or...

Tumor Immunotherapy
Immunotherapy is a treatment that boosts or manipulates the immune system to fight diseases, including cancer. For instance, by stimulating an immune response through vaccinations against viruses that cause cancers, like hepatitis B virus and human papillomavirus, these diseases can be prevented. Nonetheless, some cancer cells can avoid the immune system due to their rapid mutation and division. The immune response to many cancers involves three phases: elimination, equilibrium, and escape.
